Answer:
41
Step-by-step explanation:
Matrix Multiplication follows a row-column format. In order to compute this, you must be familiar with vector dot products.
With that in mind, lets get straight into it.
The order that matrix multiplication follows means that the terms in the result are filled in left to right, then top to bottom.
Therefore, a21 will be the 3 value that is computed. This is important becuase this allows to directly compute a21, instead of using up a lot of time computing all the values before.
As a21 is located in the bottom row 1st column, we take the dot product of the 2nd row in matrix 1 and the 1 column in matrix two.
So we have:
(7 2) dot (5 3) = 7*5 + 2*3 = 41
These are from least to greatest 1.6,1.64,16,4,16.009
Answer:
33+15w=3w-w+4w
33+15w - 15w=3w-w+4w -15w
33 = 2w + 4w -15w
33 = 6w -15w
33 = -9w
33/9 = -9/9w
3.66 = w
Step-by-step explanation:
33+15w=3w-w+4w
33+15w - 15w=3w-w+4w -15w
33 = 2w + 4w -15w
33 = 6w -15w
33 = -9w
33/9 = -9/9w
3.66 = w
this gives
total area of the field = 4655 sqyrd + 1884.79 sqyrd = 6539.79 sqyrd
cost of fertilising 1 sqyrd = $ 0.08
so cost of fertilising 6539.79 sqyrd = 6539.79 * $ 0.08 = $ 523.18
Answer:
A.
Step-by-step explanation:
Since the 2 shorter sides are greater than the longest side when added, it meet the triangle inequality thoerem. Triangle Inequality Theorom: The longest side of a triangle is less then the 2 shorter sides added.
